1%; ATTORNEY Patented Oct. -6, 1931 PATENT OFFICE FREDERICK ENGEL, OFMIAIKISBUEG, OHIO MEANS FORJVIAKING ROUND IEILES OF SLI-VER IN CORDAGEMACHINES A pplicationfiled- Ma 12;

My invention. relates to improvements in means; for making round pilesof sliver in cordage machines, and more particularly to automaticpil'ers for attachment to breakers and Spreaders employed; in thepreparation of sliver for the manufacture of rope.

It is oneof the principal objects ofmy invention to provide an;automatic piler that will produce a circular-pile of sliver.

It-is another object of my invention toprovide an: automatic piler thatwill produce a circular pile, of sliver whose v adjacent layers areeccentric, thus to produce an eccentric piling ofthe layers to renderthe pile less w liable to damage in handling.

I havea-lsoproduced an automatic piler of very simple structure,operable entirely from the breaker or spreader and eliminating auxiliarymechanism on the floor; to shift the m sliver receptacle to assist thepiling action.

Other important features will be disclosed: in the fol-lowingspecification: andfl subjoined claims.

Figure 1 is a perspective view of my auto- 25 matic piler attached to aconventional breaker; Figurez2'is anienctview-of my'automatic pilen.Figure 3' is a sectional view taken on the line 3-3 f Figure 2; Figure 4is an end view of my automatic piler. Figure is a detail view'of theindexing mechanism. And' Figure 6 ista detail view taken on the line 6-6of'Figure 2; I

Referring to Figure 1 for a detailed d6? scription. of my invention. thenumeral 1. indicates: a conventional breaker or spreader employed in themanufacture of-rope and having side frasmes2: and 3 from thereazr end Iofwhich the feed rollers are removed Bolted to the top (if the: sideframesand inclined rearwardly" therefrom are two brackets 4 and 5 ofchannel section.

Securedi to the rear vertical face of these brackets are two bearingsupports 6 and 'Z joined together across the top face thereof byacha-nnel support 8.. (See Figures 1 and 2.)

The: supports 6' and '7, have rectangular openings 9' and 10respectively to receive in each a bearing block. 1l. for shaftextensions 12 and 13 of a. roller 14.

On the. outer face of each support there is 1930. Serial No. 451,578.

a cylindrical boss 15, threaded to receive an adjusting screw 15 at itsouter end to effect a. variable pressure through a compression spring 16inserted between the end of the rectangular openin s 9 and 10 and thehearing blocks 11 on the roller 14.

Adj a'cent the roller 14'is a stationary roller 17 having shaftextensions that are journaled in the upper ends of the brackets 4 and 5,the shaft extension 19 being shown in F igure 4.

Mounted on the shaft extension 19 between the roller 17 and the bracket5 is a sprocket 20. On the lower roller shaft 21 of the breaker orspreader 1 is a similar sprocket .(not shown) and adapted to receive asprocket :chain 23 passing around the sprocket 20, downward under anidler 24, around the unseen sprocket to thus impart motion to the upperrollers-14 and 17. Figures 1, 2 and 3.)

Secured on the top of the support 8 and adjacent the support 4 is avertical frame member 26. At the opposite end of the support 8 andbetween the rollers 14 and 17' and the support 5 is another verticalframe member 27.

I Bolted to the uppper ends of the frame members 2627 is a gear bracket28 having at its center point a depending boss 29. (See Figure 2.) Theboss 29 has a central aperture 30 to receive a shaft extension 31 of abevel gear 32. The shaft is retained within the boss by means of awasher 33 and a lock nut 34 on the upper end of the shaft 31.

Between the boss 29 and the upright 26, and integral with the bracket 28is a bearing 35 to receivethe shaft 36 of a bevel pinion 37 meshing withthe bevel gear 32.

Attached to the outer end of the shaft 36 is a sprocket 38, and attachedto the left shaft extension of the roller 17 is another sprocket 39 overwhich a sprocket. chain 40 passes to the sprocket 38. Now, as therollers 14-17 are rotated, motion will be imparted to the bevel gear 32through the above sprockets and chain. 7

Bolted between the frame members 2627 and below the gear 32 is a bracket41 having a central aperture 42 in alinement with the (See. 7

ar 32. (See Figures 2 and 3.) Formed tween two flat plates 43 "Pl,bolted to the bottom of the bracket 4C1, is a spherical recess 45preferably formed of Babbitt metal. On the opposite faces of the placesl3et l are conical depressions 46 connecting with the recess 45. (SeeFigure 3.)

Contained within the recess 45 is a ball 47 integral with a rod 4:8whose lower end 49 extends through the depression 4L6 in the plate 44and has secured to the lower end thereof a plate 50.

Attached to the plate 50 is an inverted U shaped rod 51 to whose lowerdepending end there is attached a guider 52. (See Fig ure 4.)

To the opposite end of the rod 51 is attached a weight 53 tocounterbalance the weight of the guider The upper end of the rod 48terminates in a ball 54 received by an elongated spherical recess 55within a gear freely mounted upon a stud 57 received by the bevel gearThe ball 54 is retained within the gear by a late 58 having a sphericaldepression 59 in its face adjacent the gear 56.

The gear 56 is eccentric to the center of the gear 32 and likewise theball socket is eccentric to the axis of the gear 56.

Meshing with the gear 56 is a second gear 60 having a ratio to the gear56 of 5 to 6. This gear has a depending hub extension 61. The gear 60 isfreely mounted on a stud 62, received by a threaded hole 63 in the gear32. (See Figures 5 and 6.)

The lower end of the gear extension has equally spaced about itsperiphery sir: radial ins 64 adapted to be engaged by an index inger 65secured to the bracket 41. Now as the gear 32 is revolved one of thepins 64. will engage the finger 65 to impart a partial revolution to thegears 56 and 60 to alter the eccentricity of the hall socket 55respective to the axis of the gear 32. This change in eccentricityeffects the radius of the circular path of the guider and the resultantdiameter of the pile of sliver.

The number of pins may be other than that herein disclosed to change thenumber of turns of sliver per layer.

As the gear 32 is rotated through the means previously described, theball 54; will travel in a circular path about the axis of the gear 32and through the ball and socket connection in the plates 43-1' willimpart a circular motion to the guider 52 to produce a circular pile ofsliver. Upon each revolution of the gear the diameter of the pile iseither reduced or increased through the indexing means previouslydescribed.

The eccentric piling of the sliver is the result of the unequaldiameters the gears and 60. in this case 6 to 5. As shown in Figure 6,the eccentricity of the ball 54: respective to the gear 32 is at itsmaximum. Now,

as the gear 32 makes one revolution, ti o linger 65 will index the gear60 1 6th of a revolution, and the gear 59 aless amount, or 5/3t' th of arevolution. It is thus seen that for one complete revolution of the gear56, the gear 60 will make 1 l/ltith revolutions and the maximumdiameters of the piles of sliver will be spaced 1/6th of a revolutionapart in the container therefor.

To prevent an overthrow of the indexing mechanism. I have provided ahexagonal shoulder 66 on the hub extension 61 of the gear 60. Contactingwith the flat faces of the shoulder 66 is a keeper 67 secured to anelongated guide 68 whose one end 69 surrounds the shoulder 66 above thepins 64 and whose opposite enlarged end 70 is provided with an elongatedslot 71 to receive the shank of ascrew 72. The latter is received by astud 753 secured to the lower face of the gear 32. (See Figure 5.)

Secured to the top of the guide 68 is an angle clip 74: having attachedto its upper end a horizontally projecting spring guide 75 to receiveone end of a compress-ion spring 76 inserted bet-ween the clip 74 and afiat surface 77 on the stud 7 f to hold the keeper G7 firmly against theshoulder 66.

Secured to the top of the support 41 above the plates 434.l is adepending guide 78 having lower forked ends 7.) through which passes therod 51 to guide the latter in its circular motion.

On the under side of the bracket 8 at each end of the rollers 1l l7 aretwo angle brackets 80-81 to support an auxiliary funnelshaped guide 82where the sliver enters the guider spout to prevent it from leaving itsnormal path through the guider. (See Figure 2.) 7
